WILLIAM F. KIESEL, JR, OF ALTOONA, PENNSYLVANIA.

STEAM-REGULATING VALVE.

To all whom it may concern:

Be it known that I, WILLIAM: F. KIESEL, Jr., a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Steam-Regulating Valves, of which the following is a specification.

This invention relates to improvements in valves for regulating the steam supply and exhaust in railway car heating systems.

In recent practice it has been generally considered essential to use a thermostatic trap in connection with the drain from the radiators in railway cars, which trap automatically opens when the temperature is low, discharging the entrained water, and when heated by escape of steam closes, thus avoiding the loss of steam. I have found that equally good results can be obtained without the use of the thermostatic trap, and with constantly open exhaust passages, providing the exhaust passages be properly arranged for the purpose.

The object of my invention, therefore, is to provide the regulating valve with a casing having an exhaust chamber and outlet independent of any valve control, which, when properly connected with the car heating sys tem, will automatically and continually discharge the water of condensation without waste of steam.

I attain my object by constructing the valve, and coupling it to the heater pipes in a car, in the manner illustrated in the accompanying drawings, in which Figure 1 represents a plan view of a portion of a railway car steam heating system; Fig. 2, a transverse section through a railway car, showing the steam heating connections and my valves as applied thereto; Fig. 3, a vertical longitudinal section through the valve; and Fig. 1, an end elevation looking from left to right in Fig. 3, with one-half sectioned on the medial line through the admission and exhaust connections.

Like numerals designate like parts in the several views.

In Figs. 1 and 2 the train line pipe for supplying the steam is shown at 1, said pipe being supported on brackets attached to the center sill of the car in any approved man ner. At the center of the car, lateral branch pipes 2 lead off from the train line pipe, and are coupled by risers 3 to the regulating Specification of Letters Patent.

valves 4 at each side of the aisle of the car. An angle tee 5 connects each valve 1 with pipes 6, which are coupled into pipes 7, leading along the car sides to opposite ends of the car, where connection is made with the ends of continuous radiators 8, which pass from end to end of the car sides, below the seats, in the usual manner. At the center of the car the radiators are connected by pipes 9 with the exhaust chambers of the valves 1, the exhaust being carried away through pipes 10, which lead vertically downward at the side of the risers 3.

Referring now to Figs. 3 and 1, which show the details of the valve construction; the riser 3 is screwed into the admission opening 11, which leads to a chamber 12, from which passages 13 lead on opposite sides of a central chamber 14 to the opposite end of the valve casing, where the passages rise and unite in a central chamber 15. From this chamber a circular passageway 16 leads to chamber 17, at the upward side of which is an elongated passageway 18 in the connection 19, by which the valve is coupled to the angle tee 5.

The passageway through the opening 16 is closed by means of the valve 20, which engages a valve seat 21, and which is further provided with a cylindrical extension 22, which passes through the opening 16, the outward edge of this extension being provided with notches as shown, one notch being somewhat longer than the others for the purpose of regulating the admission of steam as the valve is opened. This notched regulating valve is not new, having been used for similar purposes heretofore. The valve 20 is fastened, as shown, to a cylindrical valve 24: in the chamber 17; the valve stem for operating the valves being fastened by a swivel connection between the two valves where joined together.

The drain, or exhaust pipe 9 is connected to the valve by being screwed into opening 26, which leads into the central exhaust chamber 14. From this chamber a restricted discharge passage 27 leads vertically downward through a short nipple 28, positioned centrally within the larger exhaust connection 29, to which the pipe 10 is coupled.

When the valve is closed, as shown in Fig. 3, there is communication from port 18, through chamber 17 back of valve 241, and

through a small hole 30, to the exhaust chamber 14, which allows any Water of condensation in pipes 6 to flow back through the valve chamber directly to the drip, thus freeing the pipes of water, and permitting the steam to pass freely therethrough to the radiators when the valve is opened. The entire system is thus drained of water by simply closing the valves.

Steam passing into chamber 12 and thence through the lateral passageways 13, heats the exhaust chamber 14:, and through its walls also heats the water of condensation passing through said chamber so that it will run freely through the discharge outlet 27, regardless of the outside temperature; the water, as it runs from the outlet, being carried away through the enlarged discharge passage formed by the connection 29 and pipe 10, which serves to protect the water discharge from direct contact with the cold air outside and obviates any danger of a freeze up at the discharge outlet.

In practice, the radiator connections will be made through 1 inch pipes, and the discharge outlet 27 will be of an inch in diameter; this constriction of the outlet, together wit-h the heating of the exhaust in chamber 14 constituting a suflicient check to the discharge of the exhaust steam and water of condensation flowing therethrough, to maintain the steam in the radiators at a proper temperature and pressure, as regulated by the admission valve 20.

\Vhen the main valve is opened, and before steam is admitted to the port 18, communication between said port and vent 30 will be cut oh by the valve 24; said valve then opening port 18 at its opposite end, in conformity with the admission of steam through the notches in the valve extension 22.

What I claim as my invention and desire to secure by Letters Patent is 1. A valve casing having a valve chamber in the upper portion thereof, an exhaust passage below said chamber, pipe connections leading from the valve chamber and back to the exhaust passage, said valve casing having steam supply passages leading along opposite sides of the exhaust passage and upward to the valve chamber from a train pipe connection positioned adjacent the discharge end of the exhaust passage and a constricted drain vent opening clownward from the exhaust passage at its discharge end, and a manually operated valve in the valve chamber adapted to regulate the admission of steam from the supply passages to the valve chamber.

2. A valve casing having separate steam supply and exhaust passages, a valve chamber in the supply passage, a regulating valve therein, a short constricted vent pipe projecting downward from the exhaust passage, and a larger and longer discharge pipe extending downward from the casing with its upper end surrounding and spaced away from the vent pipe.

3. A valve casing having separate steam supply and exhaust passages, a valve chamber in the supply passage above the exhaust passage, a regulating valve in said chamber, said valve casing having a duct leading from the valve chamber to the exhaust passage, and means whereby said duct will be opened by the closing of the valve and closed by the opening of the valve.

In testimony whereof I have aflixed my signature, in presence of two witnesses.
